Erector / Meccano is a nice open ended STEM toy that could use some disruption and metrication and modernization and no themed disney licenses please.
Unfortunately there is this strange attractor that sucks everyone who trys it into "I wanna make kids version of 80/20 because 80/20 is both cool and insanely expensive" leading to "heres my custom aluminum extrusion of immense expense that works with nothing out there, but now I know why 80/20 is incredibly expensive" leading to "remember those guys?"
